Itis the primary object ofthe inventionto provide a bearing plateandanchor suitable for supporting and'lixin'g' the jposition of a joistwith reference to a masonry wall made of hollow building block such forexample as hollow clay tile. It my purpose to. provide for distrilnltingthe weightof the joist and the parts suppportedthereby-uponseveral loadcarrying'webs of the hollow tile, while anchoring the joist againstlongitu linal dis cement with reference to the wall.

In ac neving these results, Ipropose toprovide a plate which isrelatively thin and'is receivable into the mortar space in the-wall,such plate having wall engaging prongs adapted to interact Withwebsolfthe hollow tile blocks. of the wallend aineans likewise.

adapted hd-interact with the joist itself. It is my further purpose todesignthe last mentioned means in such a way that if the joist shouldbecome burned through or broken in a fire orother accident, it woulddisengage itself frointhe securing means fixing it to the anchor andwould fall without destroying the wall.

In the drawings Figure l is a perspective view of a fragment of wallshowing my improved bearing plate and joist anchor in place therein;

'lhis application is a companion of my copending application, executedAugust 22nd, 1928 and. entitled Load bearing tile. The tile hereindisclosed is the same as the tile to which such applicationrelatesand'the bearing plate and joist anchor which forms the subject matter ofthis application is incidentally disclosed in the companion case.

While it-is not essential to this invention that the tile of the wallshould be of the specialform illustrated in my companion applicationabove referred to, it will nevertheless be obvious that such form oftilelends itself to the use of this bearing plate and 1a rts areidentified by similar refer-.

The individual tile are shown at 5 and it-will beobserved that they are provided with end opening recess at 6 which arecomplementary to form a co similar to the cells 7 and 8 into which thetile is divided by means of its variously disposed internal webs andpartitions. Access to the cell. formed by the uxtaposition of recesses 61s had by breakmg away the inner wall and adjacent Web 9 and 10 of-thecon tiguou s' ends of tile 5 at the point where the jois is to come;"The end of the joist 11 is beveled, as shown at 12, and projects intothe complementary recesses 6v through the opening thus formed.

at will be obvious 'lrom a study of the eX- posed upper surface of thetile 5 that if the joist were allowed to bear directly upon such centralportions of the underlying tile as might be engaged by its extremitythere would be a severe load upon a very few webs therebeneathl It isthe primary function of the bearing plate 15 to distribute the load andto this end the plate is made sufficiently broad so that it rests uponseveral webs of the tile includlng particularly the webs 16,:

17,- 18, and partition 10 and wall 9. It will be obvious,'therefore thatthe bearing plate 15 will underlie the whole of the combined recesses 6into which the oist projects.

The bearing plate 15; held inposition not only by means of the mortar inwhich-'itis seated and by means of the tile and the oist;
